Install Bay IBNF50 Noise Filter 50 AMP Each

After read many reviews for noise filters, I took a risk on this one. I wanted a 20 amp filter for my android head unit installed in my 2002 Honda CR-V with aftermarket alternator. (NAPA Brand). I had a background high frequency buzz that was RPM based and it was very annoying. The IBNF50 arrived overnight and I popped the metal back off to inspect the solder joints. Minimal build quality, but functional. Double sided tape provides anti-grounding protection to the metal box. I desoldered the provided wires (that were very thick and could handle 50 amps) and directly soldered it into the wire harness on the back of the Android radio. I used the yellow power for Vin and Vout and spliced directly into the harness ground rather than the car body. I reassembled the box, taped it up on the wire harness so it wouldn't create any wire stress and fed it all back into the dash. 100% cessation of alternator noise. Very happy with this solution. Given that the head unit has a 20 amp fuse it will never pull enough amps to saturate the noise filter windings. I will buy this again for other filter needs.

Quick ten minute install and seems to have completely eliminated my alternator-induced whine.

I have an old MSD ignition with a new Aurora Radio that had very loud feed back from my ignition system. After installing this noise filter in line with the power to the radio (Radio not installed), the noise from the ignition was removed, or so I thought. After installing the radio (big job) mounting the noise filter on the fire wall up out of sight and going for a ride, there is noise from the ignition! Fortunately the noise is reduced about 80 %. Before the noise filter, the ignition noise was louder than the music. After installing this noise filter the music is louder than the ignition noise. However the ignition noise is still there when I bring up the RPMs.

The actual part is well built, although the cables could be a bit longer or a different ends. Didn't solve my issue but I am going to keep it and end up using it for a different project.

Great product. Works well.

In my experience, it made absolutely no difference. Noise still present. It didn't even reduce it by a bit. It's fully there. I saw lots of positive reviews so I had faith on it, not anymore after trying myself

Mine came with The metal cap not glued correctly. So I can see the inside. And I never put hardware on my car without testing. I'm glad it arrived slighly opened. I didn't tested it at all for the moment. But It need more insulation for pcb connection, reflow the unmelted solder, and check crimping of cables. The connexion of cable: solder unmelted completely, and not completely crimped. Wire are really thick for this price it's a good point. For the pcb itself it seem' well made. between IBNF 50 and IBNF 30 it's the same pcb but wire for the transformer is really thicker on IBNF 50 due to the fact it's made for 50amps. I don't think the brand try too fool you. But before plugging this in do what I said. And instal cable fixation in all possible holes of the pcb. I will made a review for ibnf 30 a

Works, all ok

Excellent! It removed the hazy noise ony car

didn’t really suppress the noise in the radio that much, slight improvement

The unit works as expected. Has nice connectors. I shaved the sides down so I could bolt them straight to my amplifiers. Good guage of wire provided. Well insulated. Flexible, braided wire. I'd certainly purchase them again! I had a loud alternator noise and my electronic aftermarket fans were quite noisy - I purchased two of them and they took all the noise out of the amps.

Works to remove alternator buzz. Wiring the ground is advised for better results. Took away the buzz at our headsets in our sport airplane

all good, works and easy install.
